[0022] A feed pipe 7 is connected through the top of the inner sleeve 1, and a clamping groove 15 is provided on the opposite side walls of the feed pipe 7. Two second communicating grooves 19 and a first communicating groove 16 are provided in the inner sleeve 1. A clamping mechanism is provided in the two second communicating grooves 19. The ends of the two clamping mechanisms extend into the opposite clamping grooves 15 and abut against the inner side walls thereof. The clamping mechanism comprises an extrusion block 14 slidably connected in the second communicating groove 19, one end of the extrusion block 14 extends into the clamping groove 15 and abuts against the inner side wall thereof, and a second spring 20 is fixedly connected between the other end of the extrusion block 14 and the inner side wall of the second communicating groove 19;

[0023] A pressing mechanism is provided in each of the two first connecting grooves 16, and the ends of the two pressing mechanisms extend into the opposite second connecting groove 19 and are tightly pressed against the inner side wall of the clamping mechanism.

[0024] The functional principle of the utility model can be explained through the following operation modes:

[0025] In the utility model, when the staff uses the utility model, the staff adds the raw materials to be burned and processed into the inner sleeve 1 through the feed pipe 7, and then the staff passes the gas through the burner to fuel the raw materials in the inner sleeve 1. The hot gas generated by the combustion in the inner sleeve 1 will enter the air guide pipe 4 through the connecting pipe 6, and the gas will enter the outer sleeve 2 through the nozzle 5, and mix with the hot gas in the outer sleeve 2 for secondary combustion, which can improve the combustion effect of the raw materials.

The refrigeration tank 13 cools the water and returns it to the water storage tank 9 at the end, thereby repeatedly cooling the water. The water temperature in the low water storage tank 9 can surround the collecting frame 11 to cool it down as a whole, thereby increasing the cooling rate of the raw materials after combustion. After cooling is completed, the staff can export it through the material guide pipe. When the device is used for feeding for a long time, the raw materials are easily accumulated in the feed pipe 7 and cause it to get stuck. The staff can press the push rod 17 to disassemble the feed pipe 7 for deep cleaning. Pressing the push rod 17 will drive the extrusion block 14 to move, and the extrusion block 14 slides into the second connecting groove 19, so that the groove 15 leaves the restriction of the extrusion block 14. The staff can disassemble and clean the feed pipe 7. After cleaning, the staff presses the push rod 17 to reset the feed pipe 7, so that the extrusion block 14 is re-stuck in the groove 15, completing the limit installation of the feed pipe 7.
